## What is CNC Lathe calculator?

This software is very suitable for the practitioners of machining, CNC lathe and ordinary lathe.
Using this software, it is convenient to calculate, program and measure the common parts or working conditions in machining.

Main functions:
1. Arc tangent point calculation: it includes a variety of common part structures. It can quickly calculate the tangent point coordinates and generate the program in real time. At the same time, it provides the function of consider cutter compensation and generate G Code program.
2. Thread calculation: query and calculate common threads, and generate processing programs in real time.
3. CNC Macro program: macro program for common processing graphics
4. Taper calculation: to calculate the taper, you can enter the distance between tool starting and tool returning, and compensate the tool tip.
5. Trigonometric function: Calculation of angle and triangle
6. Diagonal calculation: diagonal calculation of quadrilateral, hexagon and polygon
7. Weight calculation: weight calculation of materials with common shapes
8. Tolerance calculation: quick query of hole shaft fit tolerance
9. Other calculations: chamfer calculation, linear velocity conversion, roughness calculation, etc

### 5/5 — Please add imperial

*2026-06-08, version 3.6*

App is wonderful, very helpful, well worth the money, but an only negative is it needs to cover imperial Inch measurements and not just Metric mm.

Also don’t think I have had one update. So what you see is what you get.

### 5/5 — Turner 128

*2026-05-15, version 3.6*

This is a great App, I use this most days with work programming profiles, definitely worth 5 star rating 👍👍👍👍👍

### 5/5 — Saved my life

*2026-02-11, version 3.6*

Had a job today that had a partial radius of 5mm from 12.5 diameter to 18.99… if you are a turner you know that finding the starting is a pain! 
I used this app and I’ve tried and tested in on a part and it works perfectly! £5.00 is crazy cheap considering what you can do… thankyou for this app… I owe you big time!

### 5/5 — Supper

*2025-12-04*

Хорошее приложение, еще бы русский язык добавить, и чтобы считать торцевые канавки, ценны бы этому приложению не было !!!

### 5/5 — Отзыв

*2025-06-25*

Всё хорошо, но можно русский язык?

### 2/5 — Price is not here in the part

*2025-05-05*

Not work suggest  English

### 5/5 — Please add imperial

*2025-01-29*

App is wonderful, very helpful, well worth the money, but an only negative is it needs to cover imperial Inch measurements and not just Metric mm.

### 5/5 — Ty

*2024-11-13*

Nice app, great help for work! Thanks

### 5/5 — Приложение

*2024-08-08*

Приложение классное,добавьте больше фигур,спасибо

### 5/5 — 希望增加异形外槽编程

*2024-03-23*

工作中常遇到外圆不对称的凹形槽，一边垂直，一边斜坡，有的上直下斜，有的上斜下直的凹槽。期待增加，谢谢！其他都很完美！
